IMPROVEMENT IN COTTON-PRESSES.

l Specification forming part of Letters Patent- No. 124,307, dated March 5, 187

Speciiication describing a new and useful Improvement in Cotton-Presses, invented by ROBERT N. VYA'IT, of Tehula, in the county of Holmes and State of Mississippi.

rlhe object oi this invention is to improve machines used for pressing' cotton and other articles or substances; and it consists in the revolviu g frictional bearings oi' the press, coustructed and arranged as hereinafter described.

In the accompanying drawing Figure l l'is an elevation of a press, to which my improvement is applied. Fig. 2 is a side view ot' one ofthe frictional bearings detached. Fig. 3 is a top view ofthe same. Fig. et is a vertical section of Fig. 3, taken on the line w x, showin g a portion of the supporting frame.

Similar letters of reference indica-te corresponding parts.

A is astationary frame, consisting of a mudsill, B, and girder C, connected together by the uprights D D. E is the press, whichis revolved upon my improved bearing by power applied by means ofthe levers F F. G G are screws, one of' which is a right and the other a left-hand-threa ded screw. 'lhese screws are revolved with the. press. They pass through the sill and girder, and en gage with the screwnuts H H, which are bedded in the sill and girder B and C, as seen in the drawing. On

the inner end ot' each of these screws is afollower, which as thepress is revolved, approach each other and press the cotton or other substance between them, orrecede from each other by reversing thc motion. The construction ot' the press Eis seen in Fig. 1. The end-frames I I are constructed together by the rods J, and the frames are con nected with the friction-caps K K by mea-ns ofthe gains L L in the lugs M of those caps. The bed-nuts H H and frictioncaps K K are grooved and ribbed, substantially as seen in Fin'. 4, so that, as the press revolves there can be no lateralmotion, land so that the screw will always be kept in acentral position and notbe subjected to undue strain or danger of facture at these points. By thus improving the frictional points the revolving press is made strong and durable; it is not liable to break or get out of order; besides the improvements render these parts ofthe press much more simple and inexpensive than they have heretofore been.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The grooved or ribbed cap K, in combination with the bed-nut H, constructed and arranged as and for the purpose described 2. rlhe lugs M M and gains L L on the cap K, substantially as and for the purposes described.
